Key Components of Energy Harvesting Systems
Energy harvesting systems comprise three main components:
- Transducer – Converts ambient energy into electrical energy.
- Storage System – Stores harvested energy in capacitors or small batteries.
- Power Management Circuit – Regulates the energy flow and maintains device efficiency.
These components work together to ensure that consumer electronics can reliably access and utilize harvested energy.
How Energy Harvesting Systems Work
The energy harvesting process starts with capturing ambient energy through transducers. This captured energy is converted into electricity, which is then stored in a small battery or capacitor. Finally, a power management circuit ensures a stable energy supply, allowing devices to run on harvested energy seamlessly.
Types of Energy Sources for Harvesting in Electronics
Various types of energy sources can be utilized for harvesting in consumer electronics:
- Solar Energy – Harvested from light sources.
